I don't know what kind of tomatoes you grew but if you have paste tomatoes you could also try drying them. I had dried a bunch one year and they were so awesome put into pasta sauces, etc. Really easy too, I just cut them in half and squeezed out the gel and seeds... which was good because then I had lots of seeds to ferment and save. Then stick 'em on the dehydrator until dry but still a little flexible. I stored mine in a vacuum sealed mason jar.
